Solution Agnostic service capabilities can be designed to be repeatedly invoked in support of multiple compositions that solve multiple problems. Application Effective recomposition requires the coordinated, successful, and repeated application of several additional patterns. Impacts Repeated service composition demands existing and persistent standardization and governance. Principles Standardized Service Contract, Service Loose Coupling, Service Abstraction, Service Reusability, Service Autonomy, Service Statelessnes, Service Discoverability, Service Composability Architecture Inventory, Composition, Service The individual capabilities of the original services can be repeatedly aggregated together with additional capabilities into different composition configurations. This enables capabilities to collectively solve the large problem for which they were originally delivered in addition to several other problems.
